worst moment of my life- PLS any advice/thoughts

Hello everyone, forgive my bad English since it is not my native language, I have been suffering from OCD for 6 years now. It started with being afraid of harming my loved ones and soon it escalated. All of this leads us here towards sexual obsessions. I was abused many times when I was a child. I don't know if that had any impact on my sexual issues. so everything lead up to a intrusive tought of what would happend if i touch myself with a picture of your parents" and I ended up paying attention to the intrusive tought and i ended up doing what my intrusive tought told me so i said to me "OCD would make me touch myself for everything i loved so what, i would do it before the anxiety attacks" and I end up in a spiral of having touched myself by several photos of my family members, friends and even my own therapist all wanting to prevent future compulsions and anxiety now I only think about taking my life, I never wanted that to happen I am not a monster who has sexual desire towards my loved ones I fell under my own intrusive thought and the only thing I think about now is taking my life life for what I've done

since february i have "POcd". Initial symptoms were thoughts, but then I did a testing compulsion during an intimate time, and I spiraled ever since. I struggle with addiction to smut. I'm cutting that out, but I feel as if it is too late. Ive never experienced this much mental, and emotional anguish in my life. On my time on this application I have given advice to others, and helped around, but I wonder if that even applies to me. Millions of times I wish I could turn back time and be more careful. I want to prevent many things, including what led me to spiral into OCD in the first place. I'm surely having an OCD episode. I have gotten a diagnosis, but I'm still not sure. I feel evil, cause unlike many here, I tested on my body sensations and it backfired (twice) I know I'm not supposed to figure out why that is the case, but now I have to live with it for the rest of my life even if its something I don't desire. This is disgusting for me, it is abhorrent. I could've never seen this coming. Day by day I've become more fearful of living with this, "OCD". I was a normal person before this, I knew what I was attracted to, I know my preferences, so why did this come about? This is singlehandedly the most painful thing that has happened to me and I have nobody but myself to blame. I am scared of death but I also would'nt mind sleeping for years on end. My parents and brother were understanding of my situation, but I failed them regardless. I don't want them to see me this way, nor do I want them to learn more of my predicament. I'm cooked. I know it, Fin, thats all folks. I'm only 20 and I already have other diagnosed mental illness so I recklessly brought upon myself another one. Its agonizing to live through, I wish this on nobody, not even my worst enemy. I can't even identify myself at this point. Its tearing me apart.

*tmi warning* I'm so worried im a P. Ive been crying daily unable to do anything else but ruminate over my real events. When i was 14 (before ocd) i was watching adult content and it was censored. The woman had similar features like hair and skin color as my niece. I remember noticing that and saying "huh i guess I'll imagine that as the adult version of my niece" and I did and after i was finished i moved on and didnt think anything was wrong. I dont know if i ever thought about that again? Its so blurry ocd keeps saying i did it again in a different time but i dont remember its too blurry and its scaring me so badly! I didnt even remember this till like literally last week and i wanted to die! Im 20 for context. When I remembered i immediately broke down in tears. I vaguely rmemeber this other thought i had of her when self pleasuring when I was 16??? I think it was a testing thought out of distress? But im not sure at all! It was extremely vague image and unrealistic i dont think I liked it but maybe i did?! Im so distressed its like i remmeber 2 versions of this particular event which is why I think its ocd false memories from there. Ive been ruminating and spiraling for almost a week. I keep crying i havent ate well at all in days ive been honestly dehydrating myself and i cannot sleep. I feel like a monster. I did the mistake of researching last night and kept comparing myself to the "criteria" of those sickos and like I felt so distressed. I also have been asking ai for hours on end everyday. I feel so distressed im literally crying rn as i write this i cant calm down i feel like this sick individual even tho I dont even like thinking of that at all i dont think I meant ill intent when i was a teen but its killing me inside. I would NEVER harm anyone nor want to or plan to, deep down i know I would never act out in those evil ways but like whats killing me is what if im attracted?! Is this a sign?! Am i one of those people?! Am i attracted to my niece bc of those 2 maybe even 3(??)thoughts years ago?! Did i mean ill intent?! Am I an actual danger?! Am I a monster??? I have so many urges to confess to my mom im so scared what this all means or could mean. I feel so alone and scared. Like legit whenever i get intrusive thoughts about gross stuff i feel disgusted and anxious and push it away. Those thoughts do not bring me pleasure whatsoever but this real event is making me doubt my own identity 😔
